GB/T 14261 bulk flotation zinc concentrate sampling, sample preparation method
JJG629 polycrystalline X-ray diffractometer
3 method summary
The sample is scanned by an X-ray diffractometer to determine the phase composition of the sample to identify whether the sample belongs to a zinc concentrate.
4 Instruments and equipment
4.1 X-ray diffractometer. in accordance with JJG629 regulations.
4.2 Air drying oven. temperature up to 105 ° C, temperature control accuracy ± 2 ° C.
5 sampling and sample preparation
Sampling and sample preparation according to GB/T 14261, the particle size of the sample should be less than 100μm, and dried at 105 °C ± 2 °C for at least 2h.
Place in a desiccator for later use.
6 sample test
6.1 Measurement sample preparation
Take an appropriate amount of sample (5) evenly into the sample frame, compress and flatten to a plane with the surface of the sample frame.
6.2 Determination
The measurement piece (6.1) was placed on an X-ray diffractometer sample stage, and an X-ray diffraction pattern of the sample was taken using appropriate measurement conditions.
See Appendix A for the measurement conditions of the X-ray diffractometer.
